Have you tried checking your laptop for spyware and such, You might also try deleting your original wireless connection. Then set up a new one. Sometimes this works. If not I am sure someone will be able to help you out.

Click on your start menu . Then go into the control panel. Once in the control panel. Click on Network and Sharing Center. Once this window opens. Click On Set up a new connection or network . It should show your old connection If I remember right. If it dose just delete. Then from in that window. Set up another one. I am not on my laptop now I am on my desktop trying to remember this. So I hope this helps

You could try going into the Control Panel. Under Administrative Tools. When the window open. Click on services. Then scroll down to WlanAutoConfig. See if this services is started. You can also try uninstalling the drivers For the wireless card then reinstalling them. You can do this by deleting the network card. Then reboot the computer, Then windows will reinstall the driver.See if this helps
